ABSTRACT:
The present invention provides fluorinated diamines and polymers formed therefrom, such as polyureas, polyurethane ureas, polyamides, polyimides, etc. The fluorinated diamines of the present invention are highly nucleophilic and are structured to provide polymeric materials having optimum surface properties. In the fluorinated diamines of the present invention, the end groups are primary amino groups which are substantially removed from the perfluoroalkyl groups. Moreover, the fluorine is present in the side chains which allows the fluorocarbon segments to migrate to the polymer/air interface, thereby providing polymer surfaces with high fluorine concentrations. As such, the polymers formed from the fluorinated diamines of the present invention have a variety of commercial applications as stain and oil resistant coatings, fouling release coatings, encapsulants for electrical devices, curing agents for epoxies, etc.
